Your customer has recently purchased a VNX to host their three Oracle RAC database
environments and automated payment processing application. The RACs and application are
differentiated as follows: ORA-PROD, ORA-STAGE, ORA-DEV, APP-PROD, APP-STAGE, and
APP-DEV.
The customer has provided you with their Enterprise Storage Policy (ESP) and is requesting that
you adhere to this policy when architecting their new VNX solution. The ESP states the following
as it relates to Oracle database storage requirements:
All LUNs must be configured as raw devices
All LUNs must be managed using ASM
No fewer than two LUNs per ASM disk group
No more than one database per RAC per RAID Group
No more than three databases per RAID Group
All data LUNs must be 1000 GiB RAID 5
All FRA LUNs must be 500 GiB RAID 1/0
No more than eight total disks per RAID Group
No fewer than four disks per RAID Group
Based on the ESP, and assuming ORA-PROD has six instances, what is the minimum number of
disks required?
